You would of course need a port multiplier to reach 4 drives per port.

That does discount the burst rate of controller to cache which is normally higher, however, from a throughput level, thats the math.

However, If you had, say a SSD with a throughput of 200MB/s, then 3 drives would reach saturation point.]]>Sep 21st 2009 11:43PMhttp://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/http://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/
A quick check on NewEgg shows only one hard drive with a SATA1 interface... and the other 70 drives are using SATA2. So, they've already stopped using the oldest interface.

In a few years, every drive will be SATA3... whether it needs it or not. They're just standardizing the interface. SATA3 will replace SATA2, in the same way SATA2 replaced SATA1. It's just the natural progression. It's nothing to freak out about.]]>Sep 21st 2009 6:34AMhttp://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/http://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/

But it might not be that simple (http://db.usenix.org/events/fast07/tech/schroeder/schroeder_html/index.html).

I can't say I fully understand what MTBF means in practice.]]>Sep 21st 2009 7:21AMhttp://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/http://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/
http://www.storagereview.com/guide2000/ref/hdd/perf/qual/specMTBF.html

Conclusion is, MTBF isn't an indicator of failure rate in a single drive, but it's not exactly a marketing gimmick either. It's safer to base the actual estimated longlevity of a single disk drive on the service life or the warranty of the drive than the MTBF.

I don't know what the industry standard is, but 5 years seems OK.]]>Sep 21st 2009 7:30AMhttp://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/http://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/hasn't been resolved. will hold out and wait and see what the verdict is on seagates

They announced a 7,200 rpm 2TB drive back in FEBRUARY. That one was the Seagate Constellation ES 2TB 7,200 rpm drive. They STILL haven't delivered any, and you still can't buy any of these ANYWHERE.

I'll note that you can't buy these Barracuda XT 2TB 7,200 rpm drives anywhere yet either. At this point I wouldn't pay a lot of attention to Seagate press releases. When it shows up at newegg, then we can get excited.

Personally I think Seagate is falling behind the curve a bit. They were late to 2TB. They ARE late to 2TB 7,200 rpm (both WD with their Caviar Black and Hitachi have 7,200 rpm drives out and shipping already). They have no SSD strategy. The only Seagate drive I've got at the moment is a 7,200 rpm 500GB laptop drive, and I used to be a huge Seagate fan.]]>Sep 21st 2009 11:50PMhttp://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/http://www.engadget.com/2009/09/21/seagate-2tb-barracuda-xt-worlds-first-sata-6gbps-hard-drive/
